Abstract:In this study, integration of three important concepts of distributed generation, D-FACTS devices, and microgrids are evaluated. The performance of a microgrid is dependent on its location, capacity, and placement of DG units and D-FACTS devices. In this paper a new method is proposed to simultaneously determine the optimal number, location, and capacity of DG units and D-STATCOM devices and optimal boundaries of electrical islands in the independent mode of microgrids. The main objective is to minimize the economic costs. The optimal locations of DG units and D-STATCOM devices should be determined to maximize the DG capacities with minimum loss in the best voltage profile and in the grid-connected mode of microgrids. Moreover, this locating besides simultaneous determination of island boundaries makes it possible to supply the maximum load in the islanded mode operation. To meet the mentioned goals, the PSO algorithm and MATLAB software are used. Analyzing the obtained results shows that the proposed method has suitable capability in optimal operation and cost management of distribution network planning.

AbstrakPada makalah ini indeks stabilitas tegangan sistem cepat (FSVSI) Kata kunci: Equivalent two-bus network, FSVSI, DSVSI, STQF, DVSI Abstract In this paper a fast system voltage stability index (FSVSI) has been proposed to assess overall system voltage stability of a multi-bus power system at a particular operating point using the concept of two bus network equivalent. A universal direct voltage stability index has also been explored to assess local (DVSI) as well as overall system voltage stability (DSVSI). An index called system transmission quality factor (STQF) has been developed to

“…Static synchronous compensators (STATCOM) and distribution static synchronous compensators (DSTATCOM) are two FACTS devices based on a voltage-source converter (VSC), which are widely used to improve voltage regulation and harmonic elimination and to balance the grid current [5,6]; they play a key role within the smart grid concept. They can therefore contribute toward enhancing power quality and obtaining a more reliable electricity grid.…”

“…The dynamic equation of the system plotted in Figure 2 can be obtained using a rotating reference 41 frame by means of Park's transformation as follows: Under the assumption that a three-wire VSC is used, the homopolar component of the 47 current i will be zero and the state-variable model of the DSTATCOM in the SRF can be written as [4,5]: sequence: in this situation, the negative sequences will convert into second-harmonic components in the 54 SRF [6,7]. …”

Electric power systems are among the greatest achievements of the last century. Today, important issues, such as an ever-increasing demand, the flexible and reliable integration of distributed generation or a growth in disturbing loads, must be borne in mind. In this context, smart grids play a key role, allowing better efficiency of power systems. Power electronics provides solutions to the aforementioned matters, since it allows various energy sources to be integrated into smart grids. Nevertheless, the design of the various control schemes that are necessary for the correct operation of the power-electronic interface is a very important issue that must always be taken into consideration. This paper deals with the design of the control system of a distribution static synchronous compensator (DSTATCOM) based on flying-capacitor multilevel converters. The control system is tailored to compensate for both voltage sags by means of reactive-power injection and voltage imbalances caused by unbalanced loads. The design of the overall control is carried out by using the root-locus and frequency-response techniques, improving both the transient response and the steady-state error of the closed-loop system. Simulation results obtained using PSCAD
